The 41-year-old Oscar winner starred in the 2013 Martin Scorsese film as Jordan Belfort, though another former Stratton Oakmont executive is suing producers over his own depiction in the movie, reported Independent online.
Andrew Greene's name is changed to Nicky Koskoff in the movie, and he claimed that the film spread untruths about him and damaged his reputation, suing for USD 15 million.
A judge rejected those original claims, though allowed him to assert that the filmmakers libelled him.
However, the judge has rejected the argument, and ordered that DiCaprio be deposed.
The actor was nominated for an Oscar for his portrayal of Belfort, known as the titular "Wolf of Wall Street".
